Phase-separated symmetry-breaking vortex-lattice in a binary Bose-Einstein condensate
(2020-01-01)
We study spontaneous-symmetry-breaking circularly-asymmetric phase separation of vortex lattices in a rapidly rotating harmonically-trapped quasi-two-dimensional (quasi-2D) binary Bose-Einstein condensate (BEC) with repulsive ...
Vortex patterns in rotating dipolar Bose-Einstein condensate mixtures with squared optical lattices
(Iop Publishing Ltd, 2019-01-28)
Vortex-lattice patterns with transitions from regular to other variety vortex shapes are predicted in rotating binary mixtures of dipolar Bose-Einstein condensates loaded in squared optical lattices (OLs). We focus our ...
Stable and mobile excited two-dimensional dipolar Bose-Einstein condensate solitons
(Iop Publishing Ltd, 2014-11-28)
We demonstrate robust, stable, mobile excited states of quasi-two-dimensional (quasi-2D) dipolar Bose-Einstein condensate (BEC) solitons for repulsive contact interaction with a harmonic trap along the x direction perpendicular ...
Metastable off-axis vortices in nonrotating Bose-Einstein condensates
(IOP Publishing, 2008-02)
We propose a scenario for studying vortices confined by nonrotating traps. For this purpose we model a polynomial trapping potential that can sustain locally stable off-axis vortices. We also describe a simple numerical ...
Symmetry-breaking vortex-lattice of a binary superfluid in a rotating bucket
(2020-02-06)
We study spontaneous-symmetry-broken phase-separated vortex lattice in a weakly interacting uniform rapidly rotating binary Bose superfluid contained in a quasi-two-dimensional circular or square bucket. For the inter-species ...

Spatial separation of rotating binary Bose-Einstein condensates by tuning the dipolar interactions
(2019-04-04)
We are pointing out relevant anisotropic effects, related to spatial separation and miscibility, due to dipole-dipole interactions in rotating binary dipolar Bose-Einstein condensates by considering symmetric (Dy164-Dy162) ...
C and Fortran OpenMP programs for rotating Bose–Einstein condensates
(2019-07-01)
We present OpenMP versions of C and Fortran programs for solving the Gross–Pitaevskii equation for a rotating trapped Bose–Einstein condensate (BEC) in two (2D) and three (3D) spatial dimensions. The programs can be used ...
Formation of vortices in a dense Bose-Einstein condensate
(AMER PHYSICAL SOC, 2008)
A relaxation method is employed to study a rotating dense Bose-Einstein condensate beyond the Thomas-Fermi approximation. We use a slave-boson model to describe the strongly interacting condensate and derive a generalized ...
